Evaluation of fractional carbon dioxide laser alone versus its combination with betamethasone valerate in treatment of alopecia areata, a clinical and dermoscopic study.

Alopecia areata (AA) is a non-scarring tissue-specific autoimmune disorder. Many therapeutic modalities are available for the treatment of AA, but none has yet proven to be uniformly effective. Fractional carbon dioxide (FRCO2) laser has been introduced as a treatment modality for AA. The objective is to evaluate and compare the efficacy and safety of FRCO2 laser in treatment of AA alone or in combination with betamethasone valerate cream. 30 patients were assigned to one of the following groups, Group A FRCO2, Group B FRCO2 plus betamethasone valerate cream or Group C (betamethasone valerate cream). Patients received eight laser sessions 2 weeks apart, treatment period was 4 months. A statistically significant decrease in SALT score, dystrophic hair and a statistically significant increase in terminal hair was observed in all groups. Patient satisfaction level and reduction in SALT score were significantly higher among FRCO2 and FRCO2 plus betamethasone valerate group. However, no statistical significant difference was found between FRCO2 group and FRCO2 combined with betamethasone valerate cream group. FRCO2 laser is a safe and effective treatment modality for AA when used alone or in combination with betamethasone valerate cream. However, it was found superior to betamethasone valerate cream monotherapy.

Preventive effects of betamethasone valerate ointment for radiation-induced severe oral mucositis in patients with oral or oropharyngeal cancer: protocol for a multicentre, phase II, randomised controlled trial (Bet-ROM study).

INTRODUCTION: This is a randomised, multi-centre, open-label, phase II study to evaluate the efficacy of betamethasone valerate ointment on radiation-induced oral mucositis in patients with head and neck cancer undergoing concomitant radiotherapy with cisplatin or cetuximab. METHODS AND ANALYSIS: The trial will take place at seven hospitals in Japan. Patients will be randomised (1:1) into betamethasone and control groups after the occurrence of grade 1 oral mucositis. In the betamethasone group, patients will use betamethasone valerate ointment five times a day, in addition to usual oral hygiene guidance. The primary endpoint is the incidence and onset time of grade 3 oral mucositis. The secondary endpoints are the incidence and onset time of grade 2 oral mucositis, incidence and onset time of oral candidiasis, completion of radiation therapy and adverse events. Target accrual is 102 patients with a two-sided type I error rate of 5% and 80% power to detect an 80% risk reduction in the incidence of grade 3 oral mucositis. ETHICS AND DISSEMINATION: This study was approved by the Clinical Research Review Board of Nagasaki University (No. CRB20-009). All participants will be required to provide written informed consent. Findings will be disseminated through scientific and professional conferences and peer-reviewed journal publication. The datasets generated during the study will be available from the corresponding author on reasonable request. TRIAL REGISTRATION NUMBER: jRCTs071200013.

Are Topical Corticoids Efficacious in Acute Irritant Dermatitis: The Evidence.

Topical corticosteroid therapies are widely utilized, despite the controversial results of corticoid therapy in irritant contact dermatitis as a local inflammatory reaction after repeated or single skin exposure to a chemical substance. Although corticoids may reduce the inflammatory response to the irritant, their antiproliferative effects may reduce skin barrier recovery while allowing further penetration of irritants if exposure continues. This overview reexamines the efficacy of corticosteroids in irritant contact dermatitis therapy, and with the minimal controlled experimental data currently available, notes the need for same-in this common clinical entity.

Patients preferences for different corticosteroid vehicles are highly variable.

Introduction: Topical corticosteroids, available in an array of vehicles are used to control a variety of inflammatory skin diseases. Patients preferences for different vehicles may affect their willingness to use treatment. We assess corticosteroid vehicle preference and potential impact of topical characteristics on adherence and quality of life in patients with psoriasis.Methods: Subjects with psoriasis were recruited from Wake Forest University Dermatology Clinic. Subjects sampled desoximetasone 0.25% spray, betamethasone valerate 0.1% cream, triamcinolone acetonide 0.1% ointment, fluocinonide 0.05% gel, betamethasone valerate 0.1% lotion, clobetasol propionate 0.05% foam, and fluocinonide 0.05% solution in a predetermined randomized order. Subjects completed a Vehicle Preference Measure, Determinants of Adherence Measure, and a Determinants of Quality of Life Measure.Results: Patients preferences for the various products were highly variable. Regarding Determinants of Adherence, patients perception of absorption of the medication was ranked as 'quite important/extremely important' by 85% of total subjects. A majority of patients rated medication side effects as 'quite important/extremely important' when asked to consider topical characteristics effect on quality of life.Discussion: There was wide variation in patient preference for topical medication vehicles used for treating psoriasis. Several vehicle characteristics were considered important to adherence. Given the marked variation in vehicle preference, topical treatment should be individualized according to patients preferences.

The vitamin D3 analog, maxacalcitol, reduces psoriasiform skin inflammation by inducing regulatory T cells and downregulating IL-23 and IL-17 production.

BACKGROUND: Psoriasis is a Th1/Th17-mediated inflammatory dermatosis treated with topical corticosteroids and vitamin D3 analogs (VD3 As). OBJECTIVE: To compare the effects of a VD3 A maxacalcitol and betamethasone valerate (BV) steroid lotion on topical imiquimod (IMQ)-induced psoriasiform skin inflammation. METHODS: Female BALB/c mice were treated with vehicle, maxacalcitol or BV lotion on the skin for 3 days, and IMQ cream for 6 days. q-PCR, H&E, immunohistochemistry and immunofluorescence studies were performed on skin samples. Additionally, mice were treated with vehicle, maxacalcitol or BV lotion for 3 days and CD4+CD25+ regulatory T cells (Tregs) and CD4+CD25- cells from each group were isolated from lymph nodes. Adoptive transfer of the cells was performed on recipient mice which were treated with IMQ cream for 6 days, and skin samples were obtained for q-PCR and H&E staining. RESULTS: Maxacalcitol and BV were comparable in regards clinical improvement, although maxacalcitol reduced the MHC Class II+ inflammatory cell infiltration more than BV in IMQ skin. While both treatments downregulated IL-17 A, IL-17 F, IL-22, IL-12p40, TNF-α and IL-6 mRNA expression levels, only maxacalcitol downregulated IL-23p19 expression. Significantly increased Foxp3+ cell infiltrations and IL-10 expression were noted in maxacalcitol-treated IMQ skin. Adoptive transfer of Treg cells from maxacalcitol-treated donor mice improved IMQ-induced inflammation clinically and histopathologically more than the recipients of Treg cells from BV-treated donor groups, showing reduced levels of inflammatory cytokines and increased IL-10 expression. CONCLUSION: These results indicate that maxacalcitol reduces psoriasiform skin inflammation by inducing Treg cells as well as downregulating IL-23 and IL-17 production.

Protective role of 6-formylindolo[3,2-b]carbazole (FICZ), an endogenous ligand for arylhydrocarbon receptor, in chronic mite-induced dermatitis.

BACKGROUND: Chronic eczema such as atopic dermatitis imposes significant socio-econo-psychologic burdens on the affected individuals. In addition to conventional topical treatments, phototherapy is recommended for patients with extensive lesions. Although immunosuppression is believed to explain its primary effectiveness, the underlying mechanisms of phototherapy remain unsolved. Ultraviolet irradiation generates various tryptophan photoproducts including 6-formylindolo[3,2-b]-carbazole (FICZ). FICZ is known to be a potent endogenous agonist for aryl hydrocarbon receptor (AHR); however, the biological role of FICZ in chronic eczema is unknown. OBJECTIVE: To investigate the effect of FICZ on chronic eczema such as atopic dermatitis. METHODS: We stimulated HaCaT cells and normal human epidermal keratinocytes (NHEKs) with or without FICZ and then performed quantitative reverse transcriptase polymerase chain reaction, immunofluorescence, and siRNA treatment. We used the atopic dermatitis-like NC/Nga murine model and treated the mice for 2 weeks with either Vaseline® as a control, FICZ ointment, or betamethasone 17-valerate ointment. The dermatitis score, transepidermal water loss, histology, and expression of skin barrier genes and proteins were evaluated. RESULTS: FICZ significantly upregulated the gene expression of filaggrin in both HaCaT cells and NHEKs in an AHR-dependent manner, but did not affect the gene expression of other barrier-related proteins. In addition, FICZ improved the atopic dermatitis-like skin inflammation, clinical scores, and transepidermal water loss in NC/Nga mice compared with those of control mice. On histology, FICZ significantly reduced the epidermal and dermal thickness as well as the number of mast cells. Topical FICZ also significantly reduced the gene expression of Il22. CONCLUSION: These findings highlight the beneficial role of FICZ-AHR and provide a new strategic basis for developing new drugs for chronic eczema.

Efficacy of topical latanoprost versus minoxidil and betamethasone valerate on the treatment of alopecia areata.

BACKGROUND: Alopecia areata (AA) is one of the most common causes of localized hair loss. There is no universally proven therapy that induces and sustains remission of hair growth in AA. OBJECTIVE: To compare the efficacy and safety of topical latanoprost, minoxidil and betamethasone valerate on hair growth in patients with AA. PATIENTS AND METHODS: Hundred patients with AA classified into five groups of 20 treated with: Group I, latanoprost 0.1% lotion; Group II, minoxidil 5% lotion; Group III, betamethasone valerate 0.1% solution; Group IV, combination of latanoprost lotion and betamethasone valerate solution and Group V, a vehicle lotion control group. RESULTS: There was a statistically significant improvement in all therapeutic groups when compared with control group and reduction of severity of alopecia tool score of scalp and beard before and after treatment for all therapeutic groups. CONCLUSION: Latanoprost, minoxidil and betamethasone valerate are effective and safe in the treatment of patchy AA. The use of latanoprost added to the therapeutic efficacy of topical betamethasone valerate in the treatment of AA and could be an effective adjunctive topical therapy for AA.

Pyostomatitis vegetans Zahlreiche blassgelbe Punkte auf entzündlich rotem Grund.

Pyostomatitis vegetans is a disease of the gingiva and the oral mucosa with noticeable, uncommon morphology. Clinical characteristics of this rare disease and considerations regarding differential diagnosis are described. Pyostomatitis vegetans is frequently associated with chronic inflammatory bowel diseases and can, thus, give a diagnostic hint at an existing ulcerative colitis or Crohn’s disease. A therapy plan for pyostomatitis vegetans is presented, which led to remission using local treatment only. The follow-up examination after one year showed that the treatment outcome had remained stable. An unexpected clinical appearance of the gingiva with small, pale pink thickenings after therapy and at follow-up is portrayed.

Differences in therapeutic effects of topically applied corticosteroid and tacrolimus on atopic dermatitis-like symptoms in NC/Nga mice.

BACKGROUND: Topical corticosteroid and calcineurin inhibitor have similar therapeutic benefits in atopic dermatitis (AD), but the differences in therapeutic mechanisms of action of these agents against AD symptoms are not fully understood. OBJECTIVE: This study was performed to examine the different effects of topical betamethasone valerate (BMV), clobetasol propionate (CBP), and tacrolimus (TAC) on itch-related behavior and dermatitis in NC/Nga mice with AD-like symptoms. METHODS: AD-like dermatitis was induced in the dorsal skin of NC/Nga mice by repeated topical application of Dermatophagoides farinae body (Dfb) ointment twice weekly for three weeks. Mice with dermatitis scores over 5 were divided into five groups with equal dermatitis scores and treated with BMV, CBP, TAC, or Vaseline (Vas) once daily for two consecutive days, or were not treated (NT). Scratching behavior was analyzed using a SCLABA®-Real system. Transepidermal water loss (TEWL) before and after treatment was measured using a Tewameter® TM210. Skin collected from each group was analyzed histologically. RESULTS: After the second treatment, dermatitis showed significantly greater improvement in the CBP and TAC-treated groups than in the Vas-treated and NT groups. The numbers of scratching bouts were significantly lower in CBP and TAC-treated mice than in Vas-treated mice. TEWL was significantly lower in TAC-, but not in CBP-, treated mice than in Vas-treated mice. Immunohistochemical examination showed that BMV, CBP and TAC did not reduce the increased densities of epidermal protein gene product 9.5- and substance P-immunoreactive fibers. The numbers of dermal CD4-immunoreactive T cells were significantly lower in BMV and CBP-treated mice than in Vas-treated and NT mice. The numbers of dermal eosinophils were significantly lower in BMV, CBP and TAC-treated mice than in Vas-treated and NT mice, with CBP showing the strongest effect. CBP significantly reduced epidermal thickness compared with Vas and NT. There were no significant differences in the numbers of interleukin-31-immunoreactive cells and mast cells, or in expression of epidermal thymic stromal lymphopoietin among all five groups. CONCLUSION: The therapeutic potency of TAC against AD-like symptoms, including pruritus, is equal to that of the corticosteroid CBP. Epidermal innervation of sensory nerves itself might not be related to the therapeutic effects of topical tacrolimus and corticosteroids in its early phase.

Corticosteroid transdermal delivery significantly improves arthritis pain and functional disability.

Arthritis is characterized by pain and functional limitation affecting the patients' quality of life. We performed a clinical study to investigate the efficacy of a betamethasone valerate medicated plaster (Betesil) in improving pain and functional disability in patients with arthritis and osteoarthritis. We enrolled 104 patients affected by osteoarthritis (n = 40) or arthritis (n = 64) in different joints. Patients received diclofenac sodium cream (2 g, four times a day) or a 2.25-mg dose of Betesil applied to the painful joint every night before bedtime for 10 days. Pain and functional disability were assessed, by the Visual Analogue Scale (VAS) and Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) scores. Redness was assessed by clinical inspection, and edema by the "fovea sign" method. C-reactive protein (CRP) was also measured; CRP can be used to cost-effectively monitor the pharmacological treatment efficacy and is increased during the acute-phase response, returning to physiological values after tissue recovery and functional restoration. All measurements were at baseline and at 10-day follow-up. At 10-day follow-up, a greater improvement in VAS and WOMAC pain and WOMAC stiffness and functional limitation scores from baseline was observed in patients treated with Betesil compared with diclofenac (all p < 0.01). At 10-day follow-up, improvement in redness, edema, and CRP levels from baseline was also greater in patients treated with Betesil compared with diclofenac (all p < 0.01). This study demonstrates the safety and efficacy of transdermal delivery of betamethasone valerate in patients affected by arthritis and osteoarthritis.

Improvement of inflammatory dermatoses severity and quality of life in patients treated with a betamethasone valerate plaster (LIBERE study).

BACKGROUND: A ready to use betamethasone valerate 0.1% (BMV) dressing was effective and well-tolerated by patients receiving chronic plaque psoriasis treatment. OBJECTIVE: Collect data related to BMV dressing used in the context of market authorization. METHODS: An observational, prospective study, including 258 patients with a maximum 4-weeks-treatment of inflammatory dermatosis with BMV 2.25 mg plaster was performed. The prescription pattern was described and the disease severity assessed using a Physician Global Assessment (PGA). Patient satisfaction as well as their quality of life (DLQI) were evaluated. Clinical evaluation was performed before and after the treatment. RESULTS: The DLQI scores improved from 10.0 ± 5.4 to 3.5 ± 3.5 points (p < 0.0001) and PGA decreased from 12.5 ± 3.1 to 4.2 ± 3.0 points (p < 0.0001). The highest DLQI and PGA improvement was reported for the eczema group. Subjects reported the test dressing was better than prior therapies with 93.5% very satisfied and 90.4% satisfied. CONCLUSIONS: The BMV dressing is well-tolerated and effective in the treatment of inflammatory dermatoses, improving both the objective signs of the disease as well as patients' quality of life.

Características socio-demográficas de las mujeres españolas con sangrado menstrual abundante. Resultados del Registro nacional de pacientes con sangrado menstrual abundante (Registro SANA) / Sociodemographic characteristics of Spanish women with heavy menstrual bleeding. Results of a national registry of patients with heavy menstrual bleeding (SANA Registry)

Objetivo. Describir las características socio-demográficas, de diagnóstico y tratamiento de las pacientes con sangrado menstrual abundante. Sujetos y métodos. Estudio observacional, transversal, multicéntrico y nacional, en mujeres en edad reproductiva (18-49 años) con sangrado menstrual abundante sin causa orgánica, en la práctica habitual de consultas de ginecología españolas. Resultados. Se incluyó a 1.039 pacientes, con una media ± desviación estándar de 37,8 ± 8,1 años. Únicamente el 52,1% acudió a la consulta por alteraciones del sangrado; el 48,0% se diagnosticó durante la consulta. Las pacientes con sangrado habitual anómalo indicaban alteraciones del sangrado relacionadas con la cantidad de forma aislada o concomitante a otras alteraciones (abundante/prolongado/irregular). Solo el 43,7% percibía cambios en el sangrado actual respecto del habitual, fundamentalmente por aumento en la cantidad. Para el tratamiento del sangrado abundante, se prescribieron anticonceptivos orales combinados (principalmente valerato de estradiol 3-2-1 mg + dienogest 3-2 μg) (63,3%), dispositivo intrauterino de levonorgestrel (14,3%) y combinaciones de tratamientos (11,9%). Conclusiones. El sangrado anómalo es prevalente, siendo una prioridad su diagnóstico mediante una evaluación adecuada (AU)

Objective. To describe the socio-demographic, diagnostic and treatment characteristics of patients with heavy menstrual bleeding. Subjects and methods. An observational, cross-sectional, multicenter, national study was conducted in women of reproductive age (18-49 years) with heavy menstrual bleeding with no organic cause attending routine gynecology consultations in Spain. Results. This study included 1,039 patients, with a mean age of 37.8 ± 8.1 years. Only 52.1% of the women attended their gynecologist due to bleeding abnormalities and 48.0% were diagnosed during the visit. Patients with longstanding abnormal bleeding reported alterations in quantity, either alone or concomitant to other abnormalities (heavy/prolonged/irregular bleeding). Only 43.7% perceived changes in current bleeding versus usual bleeding, mainly due to an increased quantity. The main drugs prescribed for the treatment of heavy bleeding were combined oral contraceptives (mainly estradiol valerate 3-2-1 mg + dienogest 3-2 μg) (63.3%), levonorgestrel intrauterine system (14.3%), and combined treatments (11.9%). Conclusions. Abnormal bleeding is prevalent. Diagnosis through appropriate assessment is a priority (AU)

[Oral hairy leukoplakia induced by topical steroids]. / Leucoplasie orale chevelue induite par une corticothérapie locale.

BACKGROUND: Oral hairy leukoplakia (OHL) is an EBV-associated condition of the oral mucosa, which is often painless. It is found predominantly in HIV-positive patients and is considered a clinical indicator of immunosuppression. OHL has rarely been described in HIV-negative patients, being found most often in association with iatrogenic immunosuppression. OHL induced by topical steroids remains extremely rare. PATIENTS AND METHODS: An 81-year-old HIV-negative woman, treated for 3 months with topical steroids for oral lichen planus, developed an asymptomatic white, corrugated, non-removable plaque with vertical folds on the lateral edge of the tongue. Associated oral candidiasis was noted. Based upon histological findings and in situ hybridisation showing numerous EBV-infected epithelial cells, a diagnosis of oral hairy leucoplakia was made. DISCUSSION AND CONCLUSION: To our knowledge, we report herein only the second recorded case of OHL induced strictly by topical steroids. Self-medication and poor adherence to dosage recommendations were noted in the patient's medical history. Physicians must be aware of the rare but nevertheless possible adverse events associated with topical steroid use, particularly when such medication is prescribed over a long period for inflammatory diseases of the oral mucosa.
